SS 904L Cold-rolled Plate: Why 904L for cold-rolled plates
Cold-rolled plate has tighter thickness tolerance and a smoother surface than hot-rolled. In SS 904L, the choice usually comes down to the medium and temperature — the rows here are the points buyers check for this exact combination.
| Why this grade | Stainless plate goes into vessels and heavy sections. SS 904L is picked for dilute sulphuric acid, phosphoric acid and chloride-bearing cooling water. |
|---|---|
| Typical service | Sulphuric acid plants — Coolers, piping and tanks for dilute sulphuric acid. |
| Matching filler | ER385 (AWS A5.9) |
SS 904L Cold-rolled Plate Thickness Range
Kanak supplies SS 904L across the sheet and plate thickness bands below. Confirm the thickness, finish and quantity on your RFQ — prices are quoted on enquiry.
| Product | Route | Thickness supplied | Typical finishes | Page |
|---|---|---|---|---|
| Sheet | Cold-rolled | 0.3 mm to below 4.76 mm | 2B, BA, No.4 (polished) | SS 904L sheet |
| Plate | Cold-rolled | 4.76 – 8 mm (thicker cold-rolled on request) | 2B / smoother surface | SS 904L cold-rolled plate |
| Plate | Hot-rolled | 4.76 – 100 mm | No.1 (HRAP) | SS 904L hot-rolled plate |
Sheet/plate boundary per ASTM A480: 3/16" (4.76 mm). The SI edition ASTM A480M uses 5.00 mm. Width conditions also apply under A480 (sheet typically ≥24" / 600 mm wide; plate definitions include a width condition). Upper limits are supply ranges for quotation, not a standard maximum. Thicker cold-rolled plate can be quoted on request.
